Basically, the phone screen is unresponsive when your not holding it or any time it's not grounded. If I put it in the car holder and then touch the screen, its very sporadic. I have compared it with the droid eris and the Moto Droid under the same conditions at the same time, and it performs flawlessly. I have tried the incredible with the screen protector and without. If I take it out of the dock and hold the phone in my hand, it works great again. It's not just the car dock either. If I set it on certain surfaces and just touch it with one finger it does the same thing.
The car dock itself has nothing to do with it. I've narrowed it down to a grounding issue. I've also tested 3 Incredibles and ALL of them do it. I am going to post another video showing it on top of a piece of styrofoam which also creates the problem. It's definitely more widespread then just a few phones. Basically, If the phone has very little ground it is unresponsive. If you ground it, either by holding it or placing it on a surface that is grounded then it solves the problem. If you plug anything into it that is grounded it solves the problem.
Here is a new video on different surfaces. It's not a car dock issue. If it is some static issue as some are saying, it works great on a eris, or a moto droid so it's not capacitive screen in general.

My goal for this thread, (now that I see it is happening to a lot of phones) is too get enough info out there so that other people can effectively recreate this problem on their phones. With enough people, I am hoping HTC or Verizon can offer a fix not just a work around.
UPDATE 5-17-10
I received 2 replacement Incredibles from Verizon. Both phones respond in the same way as the original. I called verizon, and they said "they are compiling a list of problems to send to HTC and they will add this one to the list". Hopefully the rep that I spoke with wasn't just trying to shut me up. I don't know... Anyway, Here is the last video I am going to do on the topic. In this I wanted to clearly show the following:
- It is not a "Capacitive" screen issue in general (MOTO Droid, and Eris are fine)
- It is a MASS DEFECT of this phone. (I am not saying ALL phones)
I am going to forward this message and the video to HTC. I will post the response. Here is the link to the new video.

not the same as yours but i have a similar issue. i ordered a few usb wall plugs from monoprice. whenever i use one of the usb wall plugs to charge, the touch screen is unresponsive. The volume rocker and power buttons, but the screen and bottom row of buttons dont work. Using the factory usb wall plugs everything works fine.

I have searched for someone having this problem and haven't found anything yet. So I apologize if I missed it somewhere. It's one of those problems that is difficult to recreate ALL the time so that's not making it any easier.

My wife has the incredible also, and it's doing the same thing in her car. Did we just get a bad batch of phones? Is this screen just crappy under those conditions? It would make this a totally useless phone if i can't use it in the car.

I've never had a capacitive touchscreen phone, so I don't know for sure; but maybe it has something to do with the relative capacitance. When you have one hand on the back and then touch the screen, maybe it senses a greater variance in the capacitance. If it's on the table or in your car cradle, maybe the variance in capacitance isn't great enough to register a touch. I'm not familiar with Android either, but maybe you can adjust the sensitivity? Just like those touch lamps, capacitive sensors are triggered by a relative change in capacitance and if it's not greater than the preset threshold, it doesn't register that you touched it.
Just an idea... again, I'm not really sure. I'm only lurking around in these forums because I have an Incredible on order. I'm just throwing some odd ideas out there. Good luck!
It is the type of charger/how you are using it! I had this issue. I could plug in via the provided charger and it would work. But I went on a trip and hadn't purchased a car charger yet so I grabbed my laptop ac/dc converter and plugged in the provided charger through it and my phone became unresponsive. If I plug it in the wall presto it works. The new car charger works as well!
I am sure it has something to do with the voltage being released through the charger.
Here are a couple of video's I did on the topic.
http://www.youtube.com/watch?v=bsKc1_wG0zg
http://www.youtube.com/watch?v=pXB1MjYM5Ks
Me too
I'm also having the same issue and I am using the Verizon OEM Holster Mount Combo (Perfect fit for Incredible, no power).
I'll post over at PPCGeeks, and AndroidForums to see if we can find a fix.

You have to use original charger ... it has voltage regulator and earth pin on the other end ... static should not travel on the screen otherwise it will do the same ..
Workarounds
I did find out that it is pretty easy to do the following:
1. Plug in either the charger or headphone jack. Either of those seems to ground it out enough... I also tried just clipping the headphone jack (metal part) into the clip part of the belt clip, and that worked, so there just needs to be SOMETHING else attached to the phone or mount that gives it more of a ground.
2. Just hold the sides (or just one side) with your thumb and ring finger while navigating with your index finger. That seems to do the trick.
Hope it helps.

I'm not seeing this issue, but this can't be the real dock for the incr... which one are you using?
Capacitive screens become less responsive in the cold.... if it's in front of an A/C vent with it blaring, that could be the root cause.

Updated the 1st post with a new video.
Same issues plus some new ones
I seem to have the same issues that were reported in the youtube videos because I have a similar car dock. I am also having the same issues as hoop762 as I also purchased the wall charger from monoprice. When I have it plugged in the touch screen does not work, the OEM charger works perfect. I also purchased the car charger from monoprice but that does not cause the same issues.
I have had another similar issue when I have it plugged into my car stereo via the audio jack and a male to male 3.5 cable. When it is plugged in and I try to listen to music withe the stock audio player it starts fast forwarding and skipping songs. If I pause the music then start it again it sometimes plays for a while but will then act a fool again. I had the same issue using pandora when it skipped songs until it I ran out of skips but i have not seen the issue in other programs. I have had this issue in and out of the car dock. I will add a video later if I can.
I replied to one of your videos (as tjowatonna)
"I have never noticed this issue on my Incredible and I just tested on a variety of surfaces using the Etherial Dialpad app (it's neat, check it out if you're a music nerd) to test and had no issues regardless of if it was placed on glass, plastic, cardboard, pillows. I didn't have any styrofoam to test."
Have you had anyone else try these tests on your phone? I'm just wondering if it's not something about your body that it doesn't like as much or that it likes more for people like me that can't reproduce this.
Again, there is no car dock specifically for the DI yet.
It looks like the edges of that generic dock have a big foamy area that might be very close to the screen.
It also looks like the phone/dock is touching the dash in the video.
I put mine on an anti-static bag on my workstation and tried to only use a finger. Everything worked just fine. I know you said you tried other areas with the same result. Do you have a screen protector on?
I'm just scratching my head here.
I can confirm this issue on my Incredible as well. For what it's worth, I have a Zagg shield on the screen, and I did *not* peel it off for testing.
In *any* situation where the phone is completely isolated from ground it seems to happen. I can reproduce the symptoms by setting the phone on a huge variety of surfaces or by placing it in my (plastic) car mount, and then trying to use it with just a single finger.
As has already been posted, touching the phone body even lightly with an additional finger while it is in this state (even one from same hand) will allow full responsiveness, as will any other sort of ground such as many cable connections. Also, the silicone case from Verizon can be installed or removed, and there is no difference either way.
I also just booted my old Hero (also has Zagg shield) to check its behavior and was unable to reproduce this, even with it sitting on a double folded rubber mat on top of a big pillow. It is 100% reproducible on my Incredible though.
So be it.
EDIT: In addition to the role that grounding clearly plays, static might be a factor too (as others have mentioned).
I tried my hardest to reproduce this affect and i was unable to. I have a new zagg screen protector i have not yet put on. I will add it and re-test again and post my results
** Update
I added on the Zagg Screen Protector and tested it again. I lost some responsiveness in general nothing still like has been demonstrated.

Thanks for testing your phone and also trying it against another capacitive screen phone.
I talked to Verizon and they are sending 2 new Incredibles as both my phone and my wife's phone have the problem. I will report my results on tuesday...

Now that I have my Incredible, I have the same issues. Fortunately, I don't use it in a car-dock very often but I do plan on occasionally using it that way. If Verizon or HTC doesn't come out with a fix, I may just see if I could find a soft rubber-like material that also conducts electricity to make a grounding pad with a wire connected to the vehicle's ground on the cradle/dock so the phone's back can make contact when docked.
Update in first post...
I ordered my device on launch day, and this thing has had none of the issues you have shown, I even put it on styrofoam just to try it all out, works flawlessly.
sorry for your bad luck.
Found out how to get into the car dock and home dock using a magnet. Might be helpful for people getting third party docks or those of you who want to make their own docks

Hello,
I'm wondering if anyone here has hardwired a spare Evo 4G into a car as a multimedia tablet? I would be interested in seeing the build with some questions i'd like answered
I have seen actual tablets installed. Id love to do something like this...
http://www.youtube.com/watch?v=stE33HD4g-c
How were you thinking of installing an evo?
Who the hell has a spare EVO hanging around?
Sent from my PC36100 using XDA App
It's too small. For a car tablet, a reasonably responsive tablet with a resistive screen would be fine.
i wanted to do something similar to what the youtube video did with the galaxy.
I just had some concerns about what to do about power on/power off, and accessing the power button. I want to build it flush against my center console.
About sizing, I placed the evo where I want it in my center console and it doesnt seem too small. I don't mind fabricating housings to make it fit, I'm just not sure about how to access the power button on the top after I make it flush with the console
John, Ive looked into similar things like this before. Thought about getting one of the el-cheapo arcos tablets or something to use as a car stereo. In regards to your concerns for the power button, I came across one article that I wish I could find for you.
This guy wanted to build tablets into headrests for his kids to play games on. He found an app that could detect when external power was removed (the car being turned off) and it started a timer that would shut down the tablet after x minutes. The hitch to that was I think the tablet he was using was designed to automatically turn on when external power was applied.
Just a thought to get the ball in your mind rolling.
oh that would be perfect, auto power off. but then there comes the q on how to get the evo to turn on with power on. only thing I can think of is to open the phone up and solder something down to the power switch and use an aux button on my keyless entry.
or maybe a custom bootloader that can detect power?
When I plug my evo in, the screen turns on, comes out of standby.

ah thats right. I can set option for leaving screen on while plugged in.
Only concern I have about doing this method is that the Evo would have to be on ALL the time then. Not particularly liking that idea incase I drain the battery all the way out while I am away from the car for the weekend or something.
use a small piece of 1/8 inch plexi. cut it to a 90 degree angle with arms about 1/2 inch long. on the back side of the mounting surface attach two brackets so the 90 degree piece sits in the middle and run a pivot through all three. make sure that the piece of the L is against the power button, and that the other leg of the L is flush with the mounting surface. now when you press on the exposed piece of the L, the other leg pushes the power button.
I've definitely dabbled in the idea, but the fact my car is 100% still under warranty made me reconsider.
Currently, I have a inexpensive mounting bracket hooked to my center console. I'm able to disconnect and reconnect when I'm enter or exit the car.
It's worked out pretty well... in a way, it makes the EVO look like it's merged with the stereo.
The tricky part was just cutting the bracket to accommodate my PowerMat back plate. Didn't have a effective tool at the time.

Hi all.
Just a simple question I guess:
How does the SGSII know when it is docked in a compatible car dock? (Auto start Car Home, etc..?)
Does the car dock have a magnet what does the trick?
I have made my own car dock for my SGSII. And it would be really nice if it automatically started Car Home when docked.
Best regards
a certain resistance level on the connectin.. different resistence lets it sense car dock vs. home dock. etc. etc.

Could you please explain?
Resistance level on the connection?
People are talking about magnets here: http://www.reddit.com/r/Android/comments/j35p0/is_there_a_car_dock_for_the_sgsii/
lol if it was a magnet the magntometre would not work.
The car dock has a resistor in the power connector it only docks when plugged in even if the power is not connected to the dock.
Hope this helps
Sent from my GT-I9100 using XDA App
IIRC the resistor is pinned to pin 1 of the USB and to ground. If you look over on the Galaxy I9000 forum there is a post somewhere there on it.

There are many of us in the Nexus 7 community who are looking to build our tablets in to our cars and other places where the power button will not be practically accessible. I am one of those people. I was wondering if anybody had any ideas on how to extend the power button?
The ribbon cable for the power and volume buttons can be seen here: http://www.ifixit.com/Guide/Installing+Nexus+7+Power+&+Volume+Button+Cable/9926/2
The header/connector on the board for the cable looks way too small to solder to and so my latest idea is finding a replacement ribbon cable that I could extend in to a tiny gauge wire and externalize from the case. From what I've been able to find so far, I think this is a ZIF FPC/FFC type ribbon cable and connector? I was thinking of something like this: http://www.mouser.com/ProductDetail...GAEpiMZZMvyL%2b65tEJ/L29YMZjxdjhiuZuU4IfHbXs= But I truly have no idea if this cable will fit? Anybody who's great with PCBs who would like to chime in?
If it helps I found a Molex catalog that has a couple connectors that look similar:

Ive been considering the nexus for my car pc aswell. Once i pick mine up i will tear it down and see if a ribbon cable could be either extended or possibly simply cut and have wires soldered to it for external power and volume. I have already designed a power supply for the nexus in the car that would also power a DAC and a HDD. I can provide the part number for the TI power chip that i used if anyone is interested. Its capable of producing 6 amps of current at 5 volts.
physical buttons suck. make all phone with only capacitive buttons,.

This is what I ended up doing. I got some good advice from another XDA'er who suggested I just pop the bubble button off the ribbon and solder to the contacts directly. In reality the bubble buttons are on a laminated sticker that I could just peel back. Then I soldered to the pads and pushed the cables out through where the rubber for the power button used to be. So far things seem to be working well, I'm a little weary of how this soldering will survive the swings in temperature being left in the car, but I guess there's only one way to find out. Observe:

Thats very nicely done. I want to do power and volume for my setup. Did the wire size you use work well or would you recommend smaller? otherwise i will need a separate volume control solution for the system. what do you have your tablet connected to for your amp and speakers?
Thanks. I used a 22 gauge wire, the smaller the better I think, as long as it's not bare. As far as amp, I'm using an aftermarket CD deck with a 3.5mm audio in. So I don't really plan on changing the volume on the tablet itself. I'll probably just keep it at 90% to avoid clipping and then adjust the gain with the CD deck. I haven't put it in my car yet though.
Steering Wheel Controls for Car PC
Has anyone tried the Joycon steering wheel control system with an android yet? It supports HID and no drivers are required for windows. It says that it cannot be programed from a linux or mac computer but just windows. Though once its programed it can be used with linux. Im thinking USB OTG plus this guy and you could control the tablet right from the steering wheel.
The solder will last fine on that job. The only thing I would be concerned about is getting false "presses" from the one lead that's soldered to the middle touching the outside ring. Perhaps just place a piece of electrical tape under it. Your other option might be to go straight from the connector the the flex plugs into. Just use a multimeter to test which pins you need to tap.
Thank you so much.

I just wanna thank the hell out of you. I have been searching and measuring that tiny little cable for about 2 hours now trying to find a connector and cable the right pitch/pins. Somehow the magical world of google brought me here. A site, despite my post numbers, I frequent very often. I'm installing the tablet in my car as well and I too needed a solution to the power button. Cant believe I didnt think to check here. You posted this just a few days ago. Crazy. Once again thank you. I should be able to pull this off no problem.
---------- Post added at 07:55 AM ---------- Previous post was at 07:49 AM ----------
Oh and by the way any issues with this so far? I dont imagine you have seeing as a switch on the to ends of the wire are doing exactly what the little foil button does. Just wanted to ask though before I commit to this in a couple of days.
I recommend if you are going to put it in a car, it needs some sort of quick release. If any stress is put on that cable, the contacts would either lift or the flex would rip pretty easily. I did my nook soldered straight to the main board and a quick release in the cable between the board and the button. I also did as much as I could to keep the cable from the back housing to board from moving by putting tape and locking the cable down when I put the back housing on.
The first picture shows the main board of the Nook. I just took off the old button and replaced it with my wiring. I used hot glue to keep it from wiggling.You can see the quick releases I used in the second picture. I just pulled them from a donor PC I had laying around.
Being a USB fan, I'd try to see if a custom USB device could do the job.
Just recently I made a USB volume control for Windows.
It works on my Nook Touch too.

Have you tried connecting a faux USB HID device (like the Arduino Leonardo) and sending arbitrary keycodes while it's "off" to see whether any might be capable of waking it up? I don't know whether that could power it up from a "cold off" state, but I'm 99% sure you could wake it up from "screen off, asleep" that way.

I haven't tried this. I've just been using my externalized power button to wake the device from both warm and cold off states. I have a CNX-2140 power supply from my old car PC setup that has an ACPI pulse. I use this to wake the device from a warm sleep.
Thanks you XDA for being here. Just solved half of the problem my friend was having for his tablet . Mounting it in a 2006 Mustang. Now, Gotta see if he can use the POGO for charging and a USB OTG for the external camera
its help!! thanks!
What do you terminate the raw wire ends to now? I'd by looking at mounting some kind of button inside the cab of my vehicle to turn it on/off. What kind of button would a person look for? Thanks
